Abstract: We have described herein a method and associated apparatus that can halt global warming with significant economic benefits. They include (1), re-scrub half the carbon dioxide emitted from calcining baking soda into soda ash to produce twice as much soda ash and twice as much ammonium chloride as comparing with the standard Solvay ammonia soda ash process; Use the ammonium chloride as sugarcane fertilizer producing fuel ethanol, and bagasse, a photosynthesized bio-fuel from carbon dioxide already presented in the earth atmosphere for power generation, and (2), expand the sugarcane plantation areas into desert oasis using desert heat to produce distilled water for irrigation, pumped by solar heated hydraulic press pumps to supplement insufficient rain forest resources on earth's continents to accelerate reaching “carbon neutral” on capture annually twenty five billion tons of anthropogenic carbon dioxide from earth atmosphere economically.
